Re: Questions about elmer-elmag-main/PermanentMagnetMachine2D
Boundary Condition 8 and 9 (in the case_3d.sif) must have a purpose. If I deactivate them the obtained results of torque and flux density are not plausible. Please see the figures below. zoom_in_Torqueplot_Comparison_BC_8and9_deactivated_in_blue_vs_activated_in_orange.png Bfield.png I greatly apprec...

Re: Questions about elmer-elmag-main/PermanentMagnetMachine2D
Adding the following lines to Solver 3 (MagnetoDynamicsCalcFields) solves the issue with 2D. Solver 3 [...] Linear System Solver = Direct Linear System Direct Method = umfpack End This is interesting because the .sifs utilizing LUA, (i.e case_coarse_opt.sif and case_2.5d.sif) do not seem to require ...

Re: Questions about elmer-elmag-main/PermanentMagnetMachine2D
Thank you for your message! I did a fresh download of the elmer-elmag repository but still get the same error. The case.sif which I use is this one: $ WM = 2*pi*1500/60 ! Mechanical Frequency [rad/s] $ PP = 2 ! Pole pairs $ H_PM = 920000 ! Magnetization at 20 deg C [A/m] $ Is = 4.2425*35*sqrt(2) ! S...

Re: 3D simulation of a Motor without application of a load
I was searching for an explanation of the Galerkin Projector in the Elmersolver-Manual. Unfortunately it is not mentioned there. But searching the Forum led to some success and valuable insights ;) The source-post of the quote below can be found here: http://www.elmerfem.org/forum/viewtopic.php?p=17...

Re: 3D simulation of a Motor without application of a load
Hi Kevin, Thank you very much! Could you please explain why it must be the Anti Rotational Projector? As I understood so far, the Anti is used when you want to project the solution multiplied by -1. As this is the full model and no symmetry projectors are used how does this led to the solution? Is t...

Re: PMSM Simulation Symmetric vs Full Model
Hi, I implemented the full-model, the half-model using periodic BC and the quarter-model using anti-periodic BC of a 4-pole motor. No load is applied. See the overview of the models below. overview_motormodels.png To simulate the torque I used the component approach. The deviations of the cogging to...

Re: Simulation of Magnetic Force with a half 3D Motormodel
I would be very thankful if somebody could have a look at my case and answer my three questions in the post above.
